1953-99-7 Usage
Uses
Used in Agricultural Industry:
3,4,5,6-Tetrachlorophthalonitrile is used as a herbicide for controlling the growth of broadleaf weeds. It functions by inhibiting photosynthesis in the target plants, which results in stunted growth and eventual death of the weeds.
However, due to its high persistence and potential to bioaccumulate, as well as its classification as a restricted use pesticide and potential human carcinogen, the use of 3,4,5,6-Tetrachlorophthalonitrile is heavily regulated in many countries. Exposure to this chemical can lead to skin and eye irritation, respiratory issues, and other health effects, necessitating careful handling and application to minimize risks to non-target organisms and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 1953-99-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,5 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1953-99:
(6*1)+(5*9)+(4*5)+(3*3)+(2*9)+(1*9)=107
107 % 10 = 7
So 1953-99-7 is a valid CAS Registry Number.

SYNTHESIS OF TETRACHLOROPHTHALONITRILE BY OXIDATIVE AMMONOLYSIS OF TETRACHLORO-o-XYLENE
Shapovalov, A. A.,Zhalgasbaeva, G. Sh.,Sembaev, D. Kh.,Suvorov, B. V.
, p. 1140 - 1143 (2007/10/02)
The production of tetrachlorophthalonitrile by oxidative ammonolysis of tetrachloro-o-xylene is described.The chlorine atoms in the ring affect the mechanism of the transformation of the alkyl groups into nitrile groups, and the latter are therefore formed independently. Tetrachloro-o-tolunitrile and tetrachlorophthalimide are side products of the reaction.
FORMATION OF AROMATIC NITRILES BY DIRECT REPLACEMENT OF THE NITRO GROUPS OF DINITROTETRACHLOROBENZENES
Milner, David J.
, p. 479 - 484 (2007/10/02)
Direct replacement of nitro by cyano groups has been effected by treatment of the dinitrotetrachlorobenzenes in refluxing chloroform with aqueous cyanide ion in the presence of a phase transfer catalyst.
